A glass bubble includes a hollow glass body having an outer surface with a diameter of between about 16 micrometers and about 25 micrometers and a surface roughness of about 0.01% to about 0.1% of that diameter. A low density sheet molding compound incorporating a plurality of glass bubbles and resin is also disclosed.

A method and apparatus for manufacturing a glass article includes flowing a glass ribbon through a housing having first and second side walls. The glass ribbon has first and second opposing major surfaces extending in a lengthwise and a widthwise direction. Ions are directed from an ionization source toward at least one of the first and second opposing major surfaces of the glass ribbon and/or an electrode directs particles away from at least one of the first and second opposing major surfaces of the glass ribbon. Such can reduce a density of particles on a major surface of the glass article formed from the glass ribbon.

Methods of forming vias in a glass-based article by laser-damage-and-etch processes including etching solutions having positive charge organic molecules are disclosed. In some embodiments, a method of forming a via in a glass-based article includes forming a damage track through a bulk of the glass-based article extending from a first surface of the glass-based article to a second surface of the glass-based article, and applying an etching solution to the glass-based article to form the via. The etching solution includes at least one acid and a positive charge organic molecule. An etch rate at the first surface and the second surface is lower than an etch rate at the damage track.

A method for forming a glass composite includes: providing a first glass member and a second glass member; activating at least a part of a surface of the first glass member to form a first activated surface, with unsaturated chemical bonds formed on the first activated surface of the first glass member; activating at least a part of a surface of the second glass member to form a second activated surface, with unsaturated chemical bonds on the second activated surface of the second glass member; and connecting at least partially the first glass member and the second glass member with each other on a contact interface at a contacting position of the first glass member and the second glass member to form the glass composite.

Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li.sup.+, K.sup.+, Mg.sup.2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.

The invention relates to a method for producing a coated, chemically prestressed glass substrate having anti-fingerprint properties. The method includes: applying at least one functional layer to a glass substrate; chemically prestressing the coated glass substrate by an ion exchange, where existing smaller alkali metal ions are exchanged for larger alkali metal ions, and are enriched in the glass substrate and the at least one functional layer; activating the surface of the at least one functional layer, where if more than one functional layer is present the surface of the outermost or uppermost layer is activated, the activating including one of several alternatives; and applying an amphiphobic coating to the at least one functional layer of the glass substrate, where, as a result of the activation process, the functional layer interacts with the amphiphobic coating.

Embodiments of the disclosure provide an apparatus and methods for localized stress modulation for overlay and substrate distortion using electron or ion implantation directly to a glass substrate. In one embodiment, a process for modifying a bulk property of a glass substrate generally includes identifying a stress pattern of a glass substrate, determining doping parameters to correct a defect (e.g., overlay error or substrate distortion) based on the stress pattern, and providing a treatment recipe to a treatment tool, wherein the treatment recipe is formulated according to the doping parameters. The process may further include performing a doping treatment process on the glass substrate using the treatment recipe to correct the overlay error or substrate distortion. In some embodiments, the treatment recipe is determined by comparing the stress pattern with a database library containing data correlating stress changes in glass substrates to various doping parameters.
